Tzaraat

If a man or woman suffering from tzaraʿat, a skin disease, has hair that turns tzahov, they are impure. In modern Hebrew, tzahov means yellow, but what does it mean in the Bible?

In Priestly law, impurity is stripped of its mythic origins in the demonic realm but still retains its dangerous, physical presence, and must be mitigated by specific acts of ritual cleansing and banishing, depending on the type of impurity. Purification from the skin disease tzaraʿat (Leviticus 13–14) offers the starkest example of such a ritual.

Were they racists?

Why is partially infected skin impure but fully infected skin pure? Mary Douglas’ insight into the polluting power of anomalies helps us make sense of this counterintuitive rule.

The Torah allows the removal of vessels from a house before the priest quarantines it for tzaraʿat, understanding impurity here not as the result of physical reality but of a human declaration. This idea is developed further by the rabbis, who apply it to other areas of Jewish law.

During the Second Temple period, the scapegoat was tied with a crimson thread. While the Torah requires a crimson thread as part of the purification ritual for tzaraʿat (skin disease), it does not mention it by the scapegoat. Nevertheless, parallel practices found in 2^nd millennium B.C.E. Hittite texts of Luwian origin imply that the use of a crimson thread is not a late innovation but an ancient part of the rite.

Already in the early 2nd millennium B.C.E., people knew that diseases were contagious, and fear of contagion plays a key role in the Torah’s laws regarding the skin ailment, tzaraʿat. What does this mean for understanding other kinds of tum’ah?

Despite its lengthy coverage of tzaraat, biblical “leprosy,” the Torah omits discussion of its cause, its infectiousness, and its treatment. Comparison to the Mesopotamian rituals pertaining to a strikingly similar disease, Saḫaršubbû, shows that these omissions were far from accidental.

The biblical portrait of Miriam can leave the modern reader with a lingering bitterness, but a closer reading highlights her prophetic role, and her willingness to challenge the social norms and pursue an alternative, redemptive course.

Following the purification period after birth, a mother must bring a חטאת –“sin offering,” despite her having committed no obvious sin. This offers us a unique glimpse into the prehistory of the Israelite cult, when apotropaic rituals (used to protect against dangerous forces) like those in other ANE cultures, were the norm.
